Before I added an aux battery, my fridge would only run on 12 volts with
the engine running ('85 GL Westy).  When I added the aux battery, I
switched the wires around (used the existing fridge relay) so that the
fridge would run off the aux battery anytime which is the typical way of
doing it.

I also added fused wires running from the aux battery up to the fuse
panel where I pulled fuses #8 and #9 and attached the aux battery wires
on the output sides of where the fuses had been.  That way all interior
lighting, the cigar lighter, the radio and, because of the way the
original wiring is, the brake lights use the aux battery.
